Thank you for your prompt reply.
The only plugins I am using are the pollypot GoFlight / XP 11 interface and XPUIPC. Additionally, I always start XP first, then other apps in order.
I did see a gentlemen on youtube using XP 10 with Sim-Avionics with great success.
Any other information you can offer would be appreciated. Is there an alternate glass package that interfaces w / XP 11 ?
